In the following image, the outlined chords are not grouped like a majority of the other chords with four notes. There are four chords later on in the last several measures that are not grouped/notated as the outlined mark chords.

The outlined notes are written the other side of the stem. Why so? Is it this way, they are easier to read perhaps?

Very straightforward. There's no room for them in the normal place! When the writer wants notes that are on adjacent line/space positions, one will have to go on the opposite side of the stem, otherwise it'd be a big black blob. I don't think there's a rule as to which go wrong side, but tidiness, thus ease of reading is probably more important, but octaves would make sense on the 'proper' side.

Do you know if there's a "rule" for when to flip, if the notes aren't right on top of eachother? In the OP's example, the notes are right after another. But could you say, flip one of the notes in a group like this? That first group, it's pretty clear the notes are D-F-A-D, but could you flip that first F in that "triplet-group" to make it more clear? Or is that usually frowned upon/not done, and you'd really only flip them when the notes are next to eachother? (Does that question make sense?)

@BruceWayne I can't think of any instance where I'd see those flipped. It would be confusing to me because I'd expect that only to be done when the notes are one step apart.

"Flipping" is allowed only for intervals of a second, not for larger ones. See my complete answer.

The book "Music Notation" by Gardner Read, second edition, page 71, has a dozen examples of how to do this correctly and incorrectly. The core of his instruction is: "The interval of a second... should be written with the stem between the note-heads. The higher pitch is always placed to the right. ...Likewise, chords containing tones a second apart should be written with the stem centered between the component note-heads of this interval. The "adjacent" tone (which creates the interval of the second) is placed to the right of the chord when the stem is upward [top 2 red rectangles in OP's question], and to the left when downward [bottom red rectangle]."

If there are an odd number of notes stacked, should the greater number of notes be placed on the "normal" side? How should the horizontal placement of accidentals vary with note head placement?

Odd or even doesn't matter, just start at the "tip" of the chord, work your way back to the stem, and put noteheads on the "abnormal" side as needed.

The layout of accidentals should approximate that of the noteheads. A full answer would have to cover cases like one on page 74, a chord of E natural, F natural, and F sharp, which looks like warheads peeling off from a MIRV on reentry. Or maybe a Feynman diagram.
